用verilog编写的1024点的fft快速傅立叶变换

MATLAB to HDL Code conversion

1、固定红色显示一个汉字或图形，显示亮度4 级可调，用一个btn 按钮实现亮度调节，亮度变化视觉效果要尽量明显。2、用从红到绿 8 级渐变色显示一个固定汉字或图形。3、分别用单字循环显示、左右滚动显示、上下滚动显示三种显示方式单色显示四个汉字或图形，显示过程中，显示方式用一个btn 按键进行切换。4、显示的图形或汉字要尽量饱满美观。

xlinx sparten 3E实验板，实现时钟闹钟功能，闹钟播放电子音乐，时钟，闹钟通过LCD屏显示。自己写的，亲测可用。                                                                                                                    

自己编的VHDL的波形发生器 做信号的可以-BOXING

节约资源型 8位*8位 运算VHDL代码，采用串行运算，8 个时钟周期完成一次运算。QUARTUS下已验证(resource conservation-8* 8 Operational VHDL code, using serial computation. 8 clock cycles to complete an operation. QUARTUS has been under test)

基于FPGA的DDS。可以产生三种波形：正弦，方波，三角波。频率分辨率0.012Hz。频率从0至25MHz任意可调。(FPGA-based DDS. Can produce three waveforms: sine, square, triangle wave. Frequency resolution 0.012Hz. Frequency is adjustable from 0 to 25MHz.)

本例源代码文件由用户按照书中的操作步骤自己生成，“Example-2-1Project_Navigator_Demo源代码”目录下为源代码的参考文件。“Example-2-1Project_Navigator_Democounter”目录下为完整的工程，包括源代码文件、综合与实现的结果文件、ISE工程文件等，可以使用ISE工程管理器打开工程，供读者参考(In this case the source code files by the user in accordance with the steps the book itself is generated, "Example-2-1 Project_Navigator_Demo source" directory as the source code reference document. "Example-2-1 Project_Navigator_Demo counter" directory for a complete project, including source code files, integrated with the realization of the outcome document, ISE project file, etc. You can use ISE Project Manager, open the project for the reader is referred to)
